Enter the part value and total value into the calculator to determine the chart percentage. This calculator can also evaluate any of the variables given the others are known.

Chart Percentage Formula

The following formula is used to calculate the percentage of a value in a chart.

CP = (PV / TV) * 100


  • CP is the chart percentage (%)
  • PV is the part value
  • TV is the total value

To calculate the chart percentage, divide the part value by the total value. Then, multiply the result by 100 to convert the decimal to a percentage.

What is a Chart Percentage?

A chart percentage is a visual representation of data in the form of a chart that shows the proportion of each category in a total. It is often used in business and research to easily understand and interpret data. The percentages are calculated by dividing the value of each category by the total value, then multiplying by 100 to get the percentage. This allows for a quick comparison between different categories and an understanding of their relative significance in the total data set.

How to Calculate Chart Percentage?

The following steps outline how to calculate the Chart Percentage.

  1. First, determine the part value (PV).
  2. Next, determine the total value (TV).
  3. Next, use the formula CP = (PV / TV) * 100 to calculate the Chart Percentage.
  4. Finally, calculate the result.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

part value (PV) = 25

total value (TV) = 80
